The Castelli Alpha 18 Sock are warm and waterproof which make the perfect sock for riding your bike in the colder, wetter months. The arch-support band keeps the sock in place. As you pedal your bike, the sock won’t bunch inside your cycling shoe. On the toe and heel where your sock gets the most abrasion, Nylon is added to ensure the sock doesn’t wear down.
